vice which will be particularly useful in lubricating springs of vehicles in an efficient',

sind convenient nianner without soiling the hands or clothes of the user and which provides a detachable container for lubricant Vwhich can be discardedwheii einpty, and a siniilarhlled .container substituted therefor.

A particular object of the inventionis the forni `of nozzle employed, as by'l the use of saine the lubricant'in the container inayv be injected between the leaves of the'springs in an efficient inanner, and as graphite or thick grease vhas been found to be inostdesirable for-such lubrication,l the nozzle of l iny device is particularly design-ed to effectively deposit such grease between theV leaves of the springs and spread san-ie'by moving the nozzle along the spring sogas to distribute tlie grease iii the niost'advantageous manner. i A Y Other objects will appear hereinafter. The invention consists inthe combinations 4and arrangements of parts hereinafter de Fig. Q-is'a sectionalside view of the de! vice'sliow'ing the nozzleof saine'inserted between the leaves of a. spring,`- A

accomplishing such Alubrication apparently 'has not .been discovered, and especially is this true lin regard to successfully placing .graphite or other thick greased-which. have "been found to Ibe the'inostdesirable for lu-A fifi bricating springs,,betweentlie leaves of such j springs. By use of iny device such greases can bequickly and-L conveniently deposited and distributed between the leaves of the spring so as'to thoroughly lubricatesa-nie. 55 n 'Incarrying out niy invention, I preferably provide av lubricating gun consisting .of a nozzle lwhich may be-'of any desirable .sizeor shape, but preferably hasfiat 'sides 2 and .tapered edges 3. The nozzle 70 'is providedwith an opening whichiconirnunicates 'with a grease" supply, and is also provided with elongated slots 5 which coni` niunicate fwith'fopening if and are disposed is 'preferablyl provided with longitudinal grooves 6, and "with transverse grooves/8; The grooves 8 inay be positioned in. any suit*- able niaiiner across the nozzle, butvI have fouiidthat either obliquely disposed grooves, crisscross grooves (for instan.ce,see Fig. 8), or broken grooves having their opposite ends staggered with respect to each other (see Fig. 7) are'inost-A desirable kfor proper operationvof the device. .The shape ofthe nozzle' l and dispositionofthe grooves thereof has be'enjfound to be iinportant as when/the nozzleisiii'oved between the spring leaves (which usually cannot be spread very niuch), the longitudinal grooves 6 retain partV of the grease? thereby preventing all of the grease being deposited'on the spring at the saine tiine, and the transverse Ygrooves Sperinit the` grease'to be r`forced out of the slots 5 into the various grooves and evenly spread therebyas Ythe'nezzle isnioved ,betweenfth'e spring leaves.- `By reason oflits tapered ledges the nozzle will not scrape the grease back andforth as-tlie nozzleisinoved bac-k and forth, but will-spread an evenflayer 100 'of grease lbetweenl the` spring leaves las itv n'ioves therebetween.`v 1

- Attached tothe rearendof the' nozzle 1 is a guard plateV 9 which may 4be of any suitable sizeor shape, but is shown as circular. The guard plate is provided'to prei vent grease coming in contact with the lingers,V and to keep the device freeA from Vgrease except attlie nozzle 1.

viiecured to and preferably integral with iio l the nozzle l is a tubular neclipiece 10, having its outer end interiorly threaded as shown at ll. 5

Attached rto the end of the tubular neckpiece l0 is a collapsible tube l2rwhich contains' graphite or other grease which it is desired to inject between the spring leaves.

The tube l2' may be oi.' any suitableV mate-H rial but is preferably tin or lead foil and is provided with a threaded nipple for detachably engaging with-the threadedend 1l ot the neciipiece l0. The tube l2 also is preferablyprovided with a stitlf wire key V13 which. is adaptedto squeeze the tube and force grease through the'nozzlel, and also 'assures complete'einptying oty the tube.

Tubes ofthis character Vmay be filled with gi'aphite'or othersuitable grease and placed on sale along with the nozzle, and may also be sold 'separately to take the plane .ot empty tubes-i ln operation, the lea-ves oit' the Y spring to be lubricated areiirst spread apart Y by any suitable means such as a clampy 14s,

and the nozzle lrinserted therebetween. rllieV key is then turnedjconipressing the tube and forcing grease out yoi the Yslots 5, and the nozzle is moved back and iiorth between the spring leaves, spreading thev grease thereon uniformly-rin the desired quantities,

y of the appended claims.

the yshape of the nozzle and the arrangement of the grooves being such thatthe grease is evenly distributed and the nozzle used like a. paddle, without likelihood of clogkging'up the openings'in the nozzle l. The device is of great'commercial value,is sim- `ple in construction and. eiiicient in `opera-- tion.V v

l/Vhile l have illustrated land described the preferred form or" construction for 'car-H rying myinvention into eil'ect, this is capable oi' variation and mvodiiioationY withoutdeparting from the spirit of the invention.

l, therefore, dofnot wishrtobe limited tothe `precise vdetails ot' construction set forth, but

desire .to avail myself of such variations and modiiications as come within the scope Having described my invention, whatY I claiinas new'and desire to secure by LettersPatent is: ,Y I. l
